[Laparoscopic nephrectomy: experimental surgical model]

Presentation of 39 experimental laparoscopic nephrectomies carried out in pig. With the animals under general anaesthesia and using 4 laparoscopic trocars the authors dissected the kidney and clipped separately the ureter, renal arteria and vein. Once these elements were sectioned, they placed the kidney inside a small plastic pouch (introduced within the peritoneal cavity through one of the trocars) and after extracting its neck through the hole in the abdominal wall created by the 11 mm trócar, they performed different intra-abdominal fragmentation procedures on the extirpated kidney. Following fragmentation testing with a 7 and 10 mm punch, resectoscopic electric loop, arthroscopic cutter and ultrasonic tissue aspiration procedures, they concluded stating that an increase in the power of these last equipment would convert them into an ideal procedure for laparoscopic exeresis of any intra-abdominal organ.
